The tools I use to create most of my works to include this are Lightwave, and photoshop.
You are looking at about 90 hours worth of work, as with all projects, there are always more to work on; nothing is ever truly finished.
My inspiration to model the interior of this subway car was boredom, so instead of playing video games I decided making a subway car was better.
My texture skills as you can see are somewhat lacking, I never have been given a proper education in the use of photoshop and learned most of what I know of lightwave on my own.
You can say that this lack of knowledge is further evidence of work to be done on my projects. To that end, comments on any of my work are always welcomed.
